How big is she? She looks to be knee-high or smaller, am I correct? Depending on size, I'd say terrier/Chihuahua mix. Maybe some beagle if she's a bit bigger. Does she have a yippy bark or a baying howl? Big sign of hound tendencies. Our neighbor has a lab/hound and you can tell by his bark; quite different from his full-blooded lab sister.
